Research on Camellia oleifera fruit harvesting machinery and sorting technology
Camellia oleifera is a unique woody oil crop in China,and the development of the C.oleifera industry is conducive to enriching the supply system of edible vegetable oil in China and promoting the economic income of far-mers.In recent years,since the plantation and production of C.oleifera in China have steadily increased year by year,more and more problems caused by traditional manual operations for the harvesting have limited the development of the C.oleifera industry.Improvement of the mechanization and intelligence applications of C.oleifera fruit harvesting and husk and grain sorting can effectively enhance operation efficiency and reduce labor costs,which is very important for the healthy development of C.oleifera industry.Firstly,the basic biological characteristics and planting status of C.oleifera were systematically introduced.Secondly,the harvesting methods of C.oleifera fruit,such as manual picking,semi-mechanized picking,mechanized picking,and intelligent picking,were summarized and classified in detail.At the same time,the sorting methods of shell and grain of C.oleifera fruit,including mechanical sorting method and machine vision sorting method,were summarized and analyzed.On this basis,the common harvesting methods of C.oleifera fruit and the sorting technology of shell and grain of C.oleifera fruit were systematically com-pared.Thirdly,the problems and development trends in C.oleifera fruit harvesting machinery and husk and grain sor-ting equipment were summarized.Finally,the overall development of mechanized harvesting and husk grain sorting of C.oleifera fruit in China at this stage and the direction of solving the problems are provided.The author systematically introduces the mechanical harvesting methods of C.oleifera fruit picking,C.oleifera fruit sorting equipment and key technologies,which can provide reference for the research and development of C.oleifera fruit picking and sorting e-quipment.In the development of the C.oleifera industry chain,mechanized harvesting,and intelligent sorting would be the future development trend.With the continuous and high-quality development of China's camellia industry,it would inject new vitality into the development of China's agriculture and forestry economy and would also create more economic income and employment opportunities for China's farmers.
